Development of hydrogen systems

Hydrogen as an energy carrier is playing an increasingly important role in the design of sustainable mobility – from private transport to heavy goods vehicles and aviation. In addition, hydrogen will contribute significantly to the defossilisation of industry and energy supply via material or energetic use. The requirements for the quantity, pressure, availability and quality of hydrogen as well as the local characteristics are as diverse as the potential applications.

Irrespective of the application of hydrogen, IAV pools its know-how from these fields to accompany concepts for economically viable hydrogen production, storage and utilization plants as well as their logistics through to implementation. The spectrum ranges from small refuelling systems, both for intralogistics and road transport, to multi-megawatt plants that produce hydrogen for the production of E-Fuels or for industrial use, for example. The top priority for the respective application is to harmonise the requirements and customer wishes with the specific conditions.

Expertise from the concept phase to the implementation of a hydrogen business model

In a first step, the supply of primary energy is therefore compared with the demand for hydrogen. If the hydrogen is to be produced in-house, the usually fluctuating sources of renewable energy are examined in more detail. If, on the other hand, the hydrogen is supplied, IAV can look at the entire upstream value chain, depending on the client’s wishes. The second step is the preliminary plant design: An essential component here is typically the coupling of the energy supply via hydrogen storage to the consumers.

«In order to ensure that neither the storage facilities nor the hydrogen production plants are too large, IAV uses specialised tools of varying complexity - depending on the level of detail - for plant optimisation.»

In addition to dynamically changing regulatory measures, such as the EU taxonomy and national laws and regulations, subsidy programmes and various models for the provision of electricity, such as power purchase agreements (PPAs), are also included as boundary conditions. In addition, the use of the by-products heat and oxygen from electrolysis is an important lever for increasing the efficiency and thus the profitability of the plants. Conceivable options are, for example, the use and distribution of waste heat via heat pumps or the use of oxygen for the treatment of wastewater.

Hydrogen plants planned by IAV thus form an essential link in sector coupling. In a third step, the optimised solution is finally refined manually. Depending on the customer’s wishes, detailed profitability and investment cost calculations can be added, as can initial area and time planning or a 3D visualisation, so that the concepts developed provide a reliable basis for decisions on how to proceed until the actual projects are implemented.

Based on the concept and the dimensioning of the plants, IAV develops the customer-specific plants further up to the implementation planning stage and implements them as a tech solution provider as a turnkey plant including commissioning. IAV covers the entire hydrogen value chain, from the generation of renewable energies, hydrogen production, processing and logistics to the use of hydrogen in various sectors.
